title: Naevus corniculatus: a new acantholytic disorder.
abstract: We describe a 33-year-old man with an unusual epidermal naevus that followed the lines of Blaschko. There were filiform hyperkeratoses, large cutaneous horns and lesions that resembled giant comedones and linear hyperkeratotic plaques. All of these lesions showed acantholysis without dyskeratosis. As the disorder is characterized by multiple small or large horn-like processes, we propose the term 'naevus corniculatus'.
